Application filed; July 13,

T00 whom it may concemf] Be it known that We, V. VA'N' DOREN and PETERO. HErrMANN, citizens of the United Statesof America, and residents,respectively, of 'Burling'ame, county of San Mateo, and State,of'C-alifornia, and San Francisco, county of San Francisco,v and Stateof California have inventedYa new and Improved Railroad Crossing, ofwhich the followingis a description. p Our invention relates to arailroadicrossing and the invention has for its general object toprovide a railroad crossing improved in various particulars, whereby theweight of the roadbed both between the rails of a track and outside ofthe track is supported through the medium of the rails on a supportingassemblage beneath the track and whereby the bed is prevented fromumping movements.

A further object of the invention is to stifl'en the rails" through themedium of the bedsupporting means and also to provide in connection withthe portion of thebed outside of the rails pier supports along the outeredge of said bed portion and to: so arrange the bed and supportingmeansthat the 'up and-down motion of therails is converted into angularmotion in the-outer bed portion with .outer, pier supports; as fulcrumsor centers. The manner and means whereby the above and other objects areattained will clearly appear from the Reference is to behad to'theaccompany ing drawingsforminga part of this specification, it being'understood that the drawings are merely'illustrative of two examples ofthe invention. 7 1 V Figure 1 is a transverse vertical section of arailroad crossing constructed in accordance with our invention, theplane of the section being indicated by the line 1-1 in Figure 2; i I

Figure 2 is a fragmentary plan view" with parts of the roadbedbrokenout;

Figure 3 is av detail in longitudinal vertical section as, indicated bythelline 3+3, Figure 1;

Figure 4 is a fragmentary transverse vertical section illustrating themodified form of roadbed on our novel supporting elements.

In embodying our invention in a railroad crossing in accordance with theillustrated example we provide a transverse supporting element 10extending between the rails A of a track. The supporting elements 10have end projections 11 to overlie and rest upon the opposed railflanges. At the outsideof the rails we provide transverse supportingmembers 12 each of which at one end has a projection 13 to! overlap andrest upona rail flange and at the opposite end each-supporting element12 has a projection 14: which rests and has support upon a shoulder 15of aconcrete pier 16 disposed outside of the outer bediportion of thecrossing. Between the tracks a concrete pier 17- vis provided in'thecrossing and formed withshoulders lS tojform rests for the outer ends 14iofth'e bed portions'be tween tWo tracks. Thus, the supporting element10 is disposed between the rails of eachtrack and a supporting element12 outside of the rails of each track. A pier "17 is provided"between'the two adjacent tracks and piers 16 at the outer sides of theoutermost bed portions of the crossing.

' The adjacentends of transverse elements 12 are linked together bysupportingbars 19 extending beneath each track rail A trans verselythereof. The supporting bars 19 prevent: depression of the track railsand transfer the load to the transverse elements 10 and 12 while'theengagement of the projecting ends 11 and 13 withl the rail flangesprevents undue jumping of the track rail or vertical displacementthereof. In the case of the elements 12, which have support at theirouter endson the concrete piers 16 or 17, in

responding to vertical play of the rails,

numeral'23' indicates bolts fastening the ends of the suppor'ting bars19"to the elements 10 and 12. At the inner and outer sides of each bedportion formed by the planks 20, that is to say, the bed betweenadjacent tracks, and outside of the outermost rails,

concrete, cement, or the like.

Each'of the'elements 1O, 12 is given a truss shape for strength and thelower edge is'made V-shaped as shown in section, Figure 3, so as to notmaterially disturb the ballast of the roadbed by the up-and-downmovements as the train'rolls over the track.

WVe would state in conclusion that while the illustrated examplesconstitute practical embodiments of our lnvention, we do not limitourselves strictly to the exact details herein illustrated, since,manifestly, the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described our invention, we claim:

-1. In a railway structure, transverse supporting elements adapted to bepositioned between rails of a track and of a length to rest on theflanges of the 1'ails, transverse supporting elements adapted to bedisposed outside of the rails of the track, means to support thesecond-mentioned transverse elements at one end on the flangesof'theadjacent rails, fixed means to support the opposite ends of saidsecond-mentioned supporting elements, and-means linking the adjacentendsof the first-mentioned and second-mentioned transverse elements andaffording support for the track rails.

2. In a railway structure, transversesupporting elements adapted to bepositioned between rails of a track and of a length to rest on theflanges of the rails, transverse supporting elements adapted to bedisposed outside of the rails of the track, means to support thesecond-mentioned transverse ele ments at one end on the flanges of'theadjacent rails, fixed means to support the 0p posite ends of saidsecond-mentioned supporting elements, means linking, the adjacent endsof the first-mentioned and secondmentioned transverse elements and'afiording support for the track rails, and longitudinally' disposedbars above and secured to-said transverse elements adapted to receive aroa'dbed between said bars.

3. In a railway structure, transverse-supp0rting., elements adapted tobe positioned between rails of a track and of a length to rest on theflanges of the rails, transverse supporting elements adapted to bedisposed outside of the rails ofthetrack, meansto support thesecond-mentioned transverse elements at one end on the flanges of theadjacent rails, fixed means to support the opposite ends of saidsecond-mentioned supporting elements, means linking the adjacent end ofthe first-mentioned and second-mentioned transverse elements andafiording support for the track rails, longitudinally disposed anglebars, means fastening said angle bars tothe transverse supportingelements adjacent to the ends of the latter, and

'a roadbed forming a filling between the angle bars.

4; In a' railway structure, transverse supporting elements havingmembers adapted to rest on the flanges of the rails of a track,transverse supporting elements adapted to be disposed outside of thetrack rails and having members at one end adapted to rest on the flangesof the rails, and piers on which the opposite ends of saidsecond-mentioned transverse elements rest and are afforded verticalmovement with the rest points on the piers as centers.

5. In a railway structure, transverse bedsupporting elements adapted tobe disposed outside of the rails of a track and having .members at oneend to rest on the adjacent flanges of the track rails, and piers onwhich the opposite ends of said transverse supporting elements may haverocking vertical movement.

6. In a railway structure, transverse supporting elements adapted to bedisposed at opposite sides ofa track rail to afi'ord support for aroadbed, and links'co'nnecting the adjacent ends of said supportingelements and affording support for a rail.

7. Ina railway, bed portions between the rails, bed portions outside ofthe rails, transverse elements affording supports for said bed portions,and means linking the inside bed supports and outside bed supports andadapted to'seat the railway rails.

8. In a'railway, bed portions between the rails, bed portions outside ofthe rails, transverse elements affording supports for said bed portions,and means'linking the inside bed supports and outside bed supports andadapted to seat the railway rails; together with fixedflpiers'formingrests for the outer bed supports at the outer ends thereof onwhich'piers the said bed supports are per mitt'ed'v'ertic'al rocking"movement.
